I think alot of work has to be done to make it a professional page.
For web-design comments:
1) I see one chuck of blue text in front of my face and I am off to find out what all these categories are.
2) There is no introduction on the main page. Leaving customers trying to figure out what to do next.
3) It makes no different from any script template so I would say it is good to find ways to customize your site.
4) The layout of your googld adwords. It is vertical and takes up alot of space. In other words, your ad space is more than your search result space. Do you think people will take interest in posting whereby their post are not being prominent?
For Usability:
I have a brief run through on each section. I would think most of the content is written right from the mind. Thus, it does not look professional in a way. Try reconstruct those sentences in a way whereby it makes you more convincing?
I hope my comments will help you in one way or another.
